Medical Treatments for Posterior Tibial Tendon Issues

The posterior tibial tendon plays a key role in supporting the arch of your foot and allowing you to walk properly. When this tendon becomes inflamed or damaged, it can lead to a painful and often progressive condition known as posterior tibial tendonitis — sometimes resulting in adult-acquired flatfoot if left untreated.

Let’s take a closer look at what this condition is, what causes it, and how it can be treated effectively.

What Is Posterior Tibial Tendonitis?

Posterior tibial tendonitis is a condition where the tendon that runs along the inside of the ankle and foot becomes inflamed or torn. This tendon connects the calf muscle to the bones on the inside of the foot and is essential for maintaining arch stability.

Over time, if the tendon weakens or tears, the arch can collapse, leading to flatfoot and chronic pain.

Causes

Several factors can contribute to posterior tibial tendon issues, including:

• Overuse from high-impact sports or activities

• Obesity or excess weight

• Trauma or injury (such as ankle sprains)

• Rheumatoid arthritis or inflammatory conditions

• Flat feet or poor foot mechanics

These conditions place extra stress on the tendon, increasing the likelihood of damage or degeneration over time.

Symptoms

Common symptoms of posterior tibial tendonitis include:

• Pain and swelling on the inner side of the ankle or foot

• Difficulty standing on tiptoe

• Flattening of the arch

• Weakness or instability in the foot

• A noticeable shift in how you walk (gait changes)

Treatment

Early treatment is essential to avoid long-term damage. Conservative treatments may include:

• Rest and activity modification

• Anti-inflammatory medications

• Custom orthotics or supportive shoes

• Physical therapy to strengthen surrounding muscles

• Immobilization with a brace or boot

In more advanced cases, surgical intervention may be required to repair or reconstruct the tendon and restore foot function.
